Monitor status of your home like temperature inside and outside of your home,light intensity inside and outside of your home, motion on the main entrance,LPG leak in the home and status of you main door. In this project 5 volt 700 mA Samsung charger is used for giving the power to the circuit and made of switch mode power supply. Simple instruction to let you know how to control an AC voltage device using an IR remote control and the Arduino.
The suggested home automation system has more features than conventional home automation systems such as an ultrasonic sensor is used for water level detection and soil moisture sensor is use for automatic plant irrigation system. Arduino based device control using Bluetooth on Smartphone project can be enhanced to control the speed of the fan or volume of the buzzer etc. This project of home automation using Bluetooth and Arduino can be used for controlling any AC or DC devices. Maker.pro needs to review the security of your connection before proceeding. FIG 5,6 From this Sensomate window, you can program the threshold values for your two lights and fan.

Consequently, providing facilities and security are becoming increasingly prominent features on mobile devices. In this paper, we have to developed a home automation system that interfaces with Android mobile devices. The mobile device and system can communicate with each other from long-range via Wi-Fi. The mobile application can be loaded and interfaces with system from any compatible device. The system then acts and respond to these commands by taking actions per commands and gives the result to the user. The user can also see the result on Android mobile application from anywhere.
A software feedback is implemented between the motor and the door hook sensor output so that when the door reaches its max position and is being shut the motor stops driving the motor to prevent any damage. Here is a simple and compact security alarm system to protect your home/shop and valuables. Besides, a ready-made Passive Infrared module is integrated with the alarm system for reliable human-motion detection. The built-in passive infrared sensor detects human movement by sensing temperature changes over the scene, and works even in the total darkness . Human body heat moving across the scene will trigger the PIR sensor, and the trigger signal will be sent to the control circuit instantly.
Bluetooth Based Home Automation Systems
In addition to this, the above paragraph provides a list of some of the project ideas of home automation systems as well. It is possible to develop the home automation system by using different technologies such as Arduino, Zigbee, GSM, WiFi, DTMF, and by using different controllers like PLC, SCADA, etc. We hope that you might have received some deep insights about this topic and a better understanding of such automation systems or android based projects. Furthermore, give your valuable suggestions and feedback in the comment section below. This system is useful for the elderly and physically handicapped people as they face difficulties while operating the loads. So, with this Android-home-control system, they can easily operate the loads with portable Android mobile phones.
With the rapid increase in the number of users of internet over the past decade has made Internet a part and parcel of life, and IoT is the latest and emerging internet technology. Internet of things is a growing network of everyday object-from industrial machine to consumer goods that can share information and complete tasks while you are busy with other activities. Wireless Home Automation system using IoT is a system that uses computers or mobile devices to control basic home functions and features automatically through internet from anywhere around the world, an automated home is sometimes called a smart home.

This creates a potential difference in between of the circuit and is fed to pin A.3 and A.2 of the microcontroller respectively. To sense the temperature we used two solid state semiconductor temperature sensors from analog devices also interfaced to the ADC input of the microcontroller. The two pins are connected to the power supply to power the sensors and the third pin is the output pin is connected to the ADC7 and ADC6 channel of the microcontroller. To sense the LPG leak in the home we used the MQ-5 LPG sensor and it is interface to the ADC5 channel input of the microcontroller.
A LINK status pin to the microcontroller from the Bluetooth UART tells it that the android client is successfully connected to the host. Next, to control two light one inside and other outside the home , a fan/AC and a television we have four relays connected to the microcontroller via the NPN transistor based buffer circuit. The relays consume a lot current while being activated and the microcontroller on any pin can source only 20mA of current so a buffer circuit is utmost indispensable between the relay and the controller. Arduino based home automation using Bluetooth project helps the user to control any electronic device using Device Control app on their Android Smartphone. The android app sends commands to the controller – Arduino, through wireless communication, namely, Bluetooth.
This sensor is connected to the digital input of the microcontroller pulled up externally. To sense the presence and motion we used the PIR sensor that has a digital output and it is also connected to the digital input of the microcontroller pulled up externally. To do so, we used the NPN transistor based H-bridge bidirectional motor driver circuit interfaced to the digital output of the microcontroller.
Android gives us tools for creating apps that looks great and take more advantage of the hardware capabilities available on each device. Android is mainly based on Linux operating system which uses java- like languages for running applications. The main purpose of us- ing android is to send the control signals from smart phone through bluetooth. As we know that Android is a popular smartphone technology, which has been developing ample mobile applications. So, to turn a smartphone or tablet as a universal remote control in place of conventional remotes is a good idea as this is the most effective and flexible automation. This makes every appliance at home as a potential accessory for smartphones.
If the sleep mode is activated and motion is detected or someone open the door, the alarm fires and alert the user. The project Smart Home Automation, demonstrates a system that can be integrated into a home/building’s electrical system and allows one to wirelessly control lights, fans, and turn on or off any appliance that is plugged into a wall outlet. The system can be controlled from a Bluetooth or Wi-Fi enabled device such as a mobile phone or laptop, while a microcontroller powered box act as the server. Thus the installation cost and hardware cost is kept to a minimum as most users already own the requisite hardware such as a mobile phone and desktop PC. Also, there are many disabled and aged people who always depends on others for their basic necessities. Serial port Bluetooth module have a Bluetooth 2.0+EDR , 3Mbps modulation with complete 2.4GHZ radio transceiver and baseband.
When an LPG leak is detected the output of the LPG sensor decrease gradually and that is being sensed by the ADC of the microcontroller. After them, we used a hook switch to sense the door whether it is opened or closed. This sensor is connected to the digital input pin D.7 of the microcontroller pulled up externally.Whe the door is closed, the hook switch is closed and the output is logic low as it bypasses the ground. When the door is open, the hool switch is also open and it bypasses logic1 throught 10k resistor to the output. To sense the presence and motion we used the PIR sensor that has a digital output and it is also connected to the digital input (pinA.4) of the microcontroller pulled up externally. When a motion is detected ,the output goes high for a few seconds and comes back to low in case of absence of motion.
Home automation is used to control and monitor electronic security systems, lighting, climate, appliances, audio or video equipment, etc. Home automation is the residential extension of building automation, and it is an automation of the home, housework, or household activity. The benefits of automation are that it is secure and saves money, time, maintenance costs, and makes life easier.
